We love chocolate. Perhaps so much so that on some level we may believe, "As long as I have chocolate, I'll be happy." This is the power of attachment at work. And based on this attachment, we create a chocolate-based philosophy and order our life prioritizing chocolate.
But sometimes, we can't get our hands on any chocolate. And when the chocolate disappears, we get nervous, upset: "Oh no! Now I'm unhappy!" But of course it's not the absence of chocolate that's making us unhappy; it's our fixed ideas, and our misunderstanding the nature of chocolate.
